Terrible! They kept postponing and finally canceled our flight. They canceled so late. We had no other options but to drive to a different city and try to find a new flight to get onto our cruise. We still aren’t there yet and might not make it.

The flight was on time. The seats are very narrow.

My only complaint is that the standing recline. I wasn’t aware of that when I booked the ticket.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

No leg room AT all extremely uncomfortable flight water even cost 5 dollars

Flight crew was great. Spirit leaves a lot to be desired in terms of comfort.

I slept the whole trip but everything else was great

Flight 5 hours late. There was zero communication from Spirit (everyone was standing at the gate waiting to board for an hour+) and we were only able to find out about delay via the website. Crew made no attempt to apologize for the delay or even explain what happened once we finally left. Missed connection as a result of the delay and Spirit was not even able to be located at the airport to help rebook or find a hotel. They 100% disappeared and I am still trying to get a refund on the missed flight. So far all they’ve offered is a $30 credit. I can’t think of anything they’ve done right so far and recommend everyone avoid this airline. I understand delays happen but they’ve made no attempt to rebook my family (traveling with 3 kids) or make this right.
